92 What is the default IPX Ethernet encapsulation?

A.) SNAP
B.) Arpa
C.) 802.2
D.) Novell-Ether
E.) SAP

Ans D

93 What must be true for two Routers running IGRP to communicate their routes?

A.) Same autonomous system number
B.) Connected using Ethernet only
C.) Use composite metric
D)Configured for PPP

Ans A

94 The following is partial output from a routing table, identify the 2 numbers in the square brackets; '192.168.10.0 [100/1300] via 10.1.0.1, 00:00:23, Ethernet1'

A.) 100 = metric, 1300 = administrative distance
B.) 100 = administrative distance, 1300 = hop count
C.) 100 = administrative distance, 1300 = metric
D.) 100 = hop count, 1300 = metric

Ans C

95 Identify 3 methods used to prevent routing loops?

A.) Split horizon
B.) Holddown timers
C.) Poison reverse
D.) SPF algorithm
E.) LSP's
Ans A B C

96 Which statement is true regarding full duplex?
A.) Allows for transmission and receiving of data simultaneously
B.) Only works in a multipoint configuration
C.) Does not affect the bandwidth
D.) Allows for transmission and receiving of data but not a the same time Ans A
Full duplex is just the opposite of half duplex. It handles traffic in both directions simultaneously.

97 Identify the switching method that receives the entire frame then dispatches it?

A.) Cut-through
B.) Receive and forward
C.) Store and forward
D.) Fast forward

Ans C
Store and forward switching receives the entire frame before dispatching it.

98Identify the purpose of ICMP?

A.) Avoiding routing loops
B.) Send error and control messages
C.) Transporting routing updates
D.) Collision detection

Ans B
ICMP is used to send error and control messages. Ping uses ICMP to carry the echo-request and echo-reply.

99Which statement is true regarding the user exec and privileged exec mode?

A.) The '?' only works in Privileged exec
B.) They are identical
C.) They both require the enable password
D.) User exec is a subset of the privileged exec

Ans D
The user exec mode is a subset of the privileged exec mode. Only a certain number of commands are available at the user exec mode.

100 Which OSI layer end to end communication, segmentation and re-assembly?

A.) Network
B.) Transport
C.) Physical
D.) Application
E.) Data-Link
F.) Presentation

101 What IP command would you use to test the entire IP stack?

A.) Stack-test
B.) Arp
C.) Telnet
D.) Ping
E.) Trace

Ans C
Because Telnet is an application and it resides at the top of the stack it traverses down the stack and up the stack at the receiving end.

102 Identify the 2 hardware components used to manage and/or configure a router?

A.) Auxiliary port
B.) ROM port
C.) Management port
D.) Console port

Ans A D
The 2 hardware ports used to configure the router are the console and auxiliary ports.


103 What is the default bandwidth of a serial connection?

A.) 1200 baud
B.) 1.544 Mbps (T1)
C.) 10 Mbps
D.) 96Kpbs

Ans B
The default bandwidth is T1.

104 Identify 2 functions of IPX access-lists?

A.) Control SAP traffic
B.) Limit number of Novell servers on a network
C.) Limit number of workstations on a network
D.) Block IPX traffic

Ans A D
IPX access lists are used to restrict IPX traffic and SAP broadcasts.

105 Identify 2 HDLC characteristics?

A.) Default serial encapsulation
B.) Open standard
C.) Supports Stacker compression
D.) Supports point-to-point and multipoint

Ans A D
HDLC is the default serial encapsulation and supports point-to-point and multipoint. It is not an open standard and does not support compression.

106 Identify 3 IP applications?

A.) AURP
B.) ARP
C.) Telnet
D.) SMTP
E.) DNS
F.) RARP

Ans C D E
ARP and AURP are not part the application layer of the TCP/IP stack. SMTP - Simple Mail Transfer Protocol, Telnet, DNS - Domain Name Services (name to IP resolution).

107 Identify 3 LAN technologies?

A.) FDDI
B.) HDLC
C.) HSSI
D.) X.25
E.) 802.3
F.) 802.5

Ans A E F
The question is asking for 3 LAN technologies, HDLC, HSSI and X.25 are all WAN technologies.

108 Identify the 4 that are not LAN technologies?

A.) HDLC
B.) FDDI
C.) 802.5
D.) HSSI
E.) SDLC
F.) Frame Relay

Ans A D E F
802.5 and FDDI are LAN technologies

109 Which OSI layer supports the communication component of an application?

A.) Data-Link
B.) Physical
C.) Session
D.) Presentation
E.) Application
F.) Transport

Ans E
Layer 7 the Application layer performs this function.

110 Identify the length of an IPX address and it's components?

A.) 80 bits, 48 bits network and 32 bits node
B.) 32 bits, 16 bits network and 16 bits node
C.) None of the above
D.) 80 bits, 32 bits network and 48 bits node

Ans D
IPX address has 2 components; network and node. The network address is 32 bits and the node is 48 bits, total of 80 bits.
Layer 4 the Transport layer performs this function.
